For Reference; 

2007-2023 Honda CBR600rr  OEM size is 525x112L x-ring chain, 16t Ft. Sprocket, 42t Rear Sprocket

2009-2020 Honda CBR600ra  OEM size is 525x112L x-ring chain, 16t Ft. Sprocket, 42t Rear Sprocket

            This 520 Conversion kit is provided with all 520 size chain and sprocket components

For QUICK ACCELERATION 15/42t gear ratio (Quicker off the line, Quicker roll on's, Easier wheelies), use a 15t front sprocket. (the -1t front sprocket is versatile because you can change back to the stock ratio with 16t and same length chain)      

For EXTREME QUICK ACCELERATION 15/44t gear ratio (stunt gearing ) Request a 15t front (-1t) and a 44t rear (+2t) **Note: Your top gear cruising rpm's will be really high, and your top speed significantly reduced. If you hate it, you can go back to a 16t front and use the same chain length. 16/44t (oem/+2t) is practically the same as 15/42t (-1t/oem) regular Quick Acceleration ratio.   

For Original Factory Supplied OEM 16/42t size sprockets are the calculated "Happy Medium" of off the line acceleration, roll on's, and reasonable high speed engine rpm's with the least amount of compromise on either top end or low end acceleration.

* EXACT OEM 16/42t IS THE DEFAULT SUPPLIED GEARING WITH THIS KIT UNLESS OTHERWISE SPECIFIED Stock size teeth 520 conversion chain and sprockets are lighter weight drive train components , but the same oem final drive ratio.

Half the Power Loss (Compared with Normal O-Ring) D.I.D’s PATENTED X-Ring construction reduces friction by twisting between the side plates instead of being squashed. Normal O-Rings and other makers’ modified O-Rings have squashed points that increase friction. The twisting action of the X-Ring disperses the pressure and minimizes power loss. X-Ring is a U.S.A. Registered Trademark of D.I.D; Daido Kogyo Co. Ltd. Japan

1.5 to 2 TImes Longer Wear Resistance (Compared with Normal O-Ring) The X-Ring’s four contact points greatly increase its sealing performance. This keeps the dirt out and the lubrication in much better than any other O-Ring.   X-Rings have the greatest wear resistance of any other type of O-Ring or Non-O-Ring chain.
